Abstract

The invention discloses a cable material and a preparation method thereof. The cable material is mainly prepared by composited materials including ethylene-vinylacetate co-polymer EVA, high-density polythylene HDPE, aluminum hydroxide, magnesium hydroxide, triotyl trimellitate, roasting zeolite powder, nano calcium carbonate powder, silane coupling agent, carbon black, titanic acid esters, oxidation inhibitor 1010 and barium stearate, which are all mixed according to a specific proportion of parts by weight. The preparation method is simple, convenient in operation and reasonable in formula of the composited materials, and the prepared cable material is high in mechanical performance and fire retardant property and resistant to high temperature, and is low in smoke and non-toxic when being burned.

Description

technical field [0001] The invention relates to a polyvinyl chloride cable material and a preparation method thereof, belonging to the field of cables. Background technique [0002] With the rapid development of the economy, wires and cables are widely used in various industries and fields. With the frequent occurrence of electrical fire accidents, the flame retardant problem of wires and cables has gradually attracted the attention of countries all over the world. When the cable burns, it releases a large amount of smoke and toxic and corrosive gas, which is a risk factor in a fire. It hinders people's safe evacuation and fire fighting work during a fire, causing serious loss of life and property. At the same time, with the development of the communication industry, the automobile industry and the computer industry, especially in many occasions such as aviation wires, automobile wires, high-temperature instrument cables, and oil drilling platform cables, it is increasingly...
